[jira] [Commented] (CALCITE-4428) Remove the equiv rel from mapRel2Subset when merging set

    [ https://issues.apache.org/jira/browse/CALCITE-4428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17243820#comment-17243820 ] 

Jiatao Tao commented on CALCITE-4428:
-------------------------------------

When rename RelNode via VolcanoPlanner#rename(RelNode rel), we may remove rel from its subset: "subset.set.rels.remove(rel)" if we found equiv rel, so we should remove the equiv rel from mapRel2Subset, or we will have lots of outdated rule match.
